RAIL-ANCHOB..

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed December 31, 1912. Serial No. 739,441`

To all `whom it rmay concern:

Be it known that I, JOHN M. Scor'r, a citizen of the United States,residing at Racine, in the county of Racine and State of Wisconsin, haveinvented certain new and useful Improvements in Rail-Anchors, of whichthe following is a specification.

My invention relates to the class of track devices, known variously asrail anchors, rail stays, or anti-Creepers, which have for their purposetocheck the tendency of railroad rails to creep longitudinally in thedirection of travel of the trains.

In one type of device of this class the device consists of clampingmembers extending around and engaging the base flanges of the rail whichhave a wedging relation one with another whereby the clamping action ofthe device on the rail is effected. For example, a device of this sortwhich has been used to a certain extent is composed of a bar extendingunder the rail provided with jaws on opposite ends and of a key or wedgewhich is driven in between one of the base flanges of the rail and oneof said jaws, the other jaw extending around and gripping the oppositebase flange. An anti-creeping device of this sort has the advantage ofbeing strong, light, simple and cheap to manufacture, but has thisserious disadvantage in that the wedge or key frequently becomes looseor backs out due to the vibration of the railV under the trains, and toother Causes.

The principal object of my present invention is to provide an expedientfor locking together the relatively movable parts of an anti-creepingdevice of this general type which will be effective, will add little ornothing to the cost of the device, and which, incidentally, will permitthe relatively movable parts of the device to be disengaged with littletrouble so that the device may be removed from the rail if occasionrequires.

The improvement constituting the invention is shown in connection with adevice consisting of a bar adapted to extend under the base of the railat the anchor provided with integrally formed jaws and of alongitudinally slotted key which is driven in between one of the baseflanges of the rail and one of the jaws of the first named member. Itwill be understood, however, that the improvement is applicable to theother constructions of the same general type.

The invention is illustrated in the accompanying drawing wherein- Figure1 shows, in elevation, a. preferred form of the invention applied to arailroad rail which appears in section. Fig. .2 is a plan view of theparts shown in Fig. l; Fig. 3, a sectional view taken on line 3 3 ofFig. 2; Figs. 4, 5 and G, an end view, a top view and an edge view,respectively, of the key or wedge member, and Fig. 7, a fragmentary planview illustrating particularly the expedient employed for locking thewedge in its operative position.

Like characters of reference designate like parts in the several figuresof the drawing.

Referring to the drawing, A designates a railroad rail and B one of theties on which it is supported. The anti-creeping device consists of abar C, preferably of malleable iron, formed at one end with a jaw Dadapted to engage one of the base flanges of the rail A and at the otherend with a jaw E larger than the jaw D. A key or wedge` member F isdriven in between the jaw E and the adjacent base flange of rail A, thejaw E being preferably formed so that it stands oblique to the edge ofthe rail base and the key F being formed with the tapered slot G for theedge of the base flange. The bar C is provided with the usual tieabutting flange H or other suitable means for holding the anti-creepingdevice in a fixed position with respect'to the road bed.

The upper surface of the key F is formed with one or more grooves orindentations I providing a shoulder or shoulders J. The jaw E terminatesin a relatively thin\flange K which overlies the grooved surface of thekey F. After the key has been driven into place the portion of the edgeof the flange K above one of the grooves I is indented or offset by anysuitable means, for example, a chisel and hammer, into the groove. Thismay be done very easily and expeditiously and does not require the useof any tools except those that are ordinarily carried by the track crew.With the edge of the jaw offset into the slot of the key the key isobviously locked against any retrograde movement. However, if theanti-creeping device has to be removed from the rails this can be radilydone by the key backward. The metal of the jaw will yield sufficientlyto permit this to be done.
